GWTUpload -最大文件大小上下文参数不起作用

Question

我想用GWT upload上传更大的文件(6MB)。默认情况下，它只允许最大大小为~3MB的文件。因此，我使用以下上下文参数调整了我的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
    <context-param>
        <param-name>maxSize</param-name>
        <param-value>102400000</param-value>
    </context-param>


    <context-param>
        <!-- max size of any uploaded file -->
        <param-name>maxFileSize</param-name>
        <param-value>102400000</param-value>
    </context-param>

但尽管如此，我还是得到了以下错误：

2015-07-23 22:26:05 ERROR UploadServlet:70 - UPLOAD-SERVLET (0d0quwXW6dcRxDl_G4ZHag) getUploadStatus: GWTU-019405167154036462 finished with error: The request was rejected because its size: 6.054 KB, exceeds the maximum: 3.071 KB

我的代码在应用程序引擎上运行，我的上传操作扩展了AppEngineUploadAction

public class MyUploadAction extends AppEngineUploadAction

在我的上传操作中，我甚至覆盖了方法"checkRequest“来什么也不做，但它也没有帮助

@Override
public void checkRequest(HttpServletRequest request) {
    logger.info("Skip all checks completly");
}

我做错了什么?我如何通过GWT upload为我的应用程序启用更大的文件？

刚刚检查过了，对我来说-更改这个参数很好：

<context-param>
    <!-- max size of the upload request -->
    <param-name>maxSize</param-name>
    <param-value>9145728</param-value>
</context-param>
